WOOD-TURNING LATHE.

Application filed The objectof my invention is to provide a wood turning lat-he of simple, inexpensive construction, which is particularly adapted for turning out handles such as used on brooms, forks, rakes and the like. lie-further object is to provide a turning lathe for the purpose above stated which may be easily and quickly adjusted to form handles for various designs.

More specifically it is the object of my invention to provide in a lathe for turning handles and the like, a series of adjustable knives which are controlled by means of a pattern. cam having a means for automatiwhich may be easily and quickly adapted to form handles of various designs by simply changing the cam member. y p 7 My invention consists in the construction,

W arrangement and combination of the various 1Z5 which on the line as manner in which to groove 19 and 55 a slot 21 designed to receive one end parts of the device, whereby the objects conten'iplatcd are attained, as hereinafter more fully set forth, pointed out 111 my claim, and

Figure is a detail sectional View taken on the line 5-5 ofFigure 4, showing the the stock is fed to the lathe. The numeral 10 indicates the base, one end of which is provided'with upright supports 11 and 12, said supports having at their upper ends boxing members 13, said boxings being designed to receive a tubular shaft 14. The central portion of the shaft 14 is provided with a drive pulley 15. The forward end of the shaft 14 is provided with a disk 16, said disk having three openings 17 elevation of my jim- 45 which extend parallel and adjacent to the shaft 14. y

The outer end of the shaft 14 is provided with a sleeve 18 slidably mounted thereon. Said sleeve 18 is provided with an annular also with forwardly extend ings pins 20 which are in alinement with the openings 17 and designed to enter said openings in certain positions of their movement. Each of the pins 20 is provided with o a AugustlS, 1924. Serial No. 732,722.

I p 7 face of the disk 16 is provided with three forwardly extending lugs 24, which are in a' radial line with theopenings 17, each of the lugs 24 is providedwith a radial groove 25.

is designed to receive a shank 26 of the cut- Said shank is pivotally that the inner ends i' nounted by pins 28, so

to swingoutwardly of the knives are free about the pivots 28. Each of the shanks 26' is provided with an opening 29 designed to receive the outer end of the corresponding link 22, said link being secured therein by means ofa pin 30. i

I flattened'to form the cutting blade 27 said blade extending first forwardly and towardthe center, then bent forwardly. Thedisk 16 'is rection as shownin Figure has its forward edge tapered and sharpened at 31. The knives are so crease or decrease the distance between the .The inner end of each arranged thatif apiece of wood were placed longitudinally through the tubular shaft 14 and the head rotated, an annularV-shaped groovewould Each of the grooves p 7 cutting edges ofthe knives, so that handles of various diameters may be formed by the simple operation of moving the sleeve 18 toward or from the disk 16.

In front of the tubular shaft 14 I have provided a square trough 32 which extends longitudinally 1 and in alignment with the opening in the tubular shaft, said trough being designed to receive aI'square stick of wood 33. The trough 32 is supported by upright members 34'from the base 10.

For feeding the stick of wood endways into the cutting knives, following mechanism:

A shaft 35 is mounted transversely above the rear end of the stick 32, while a shaft 36 is mounted transversely beneath it. The

I have provided the shaft 35 is provided with afeed roller 37,

gage the upper and lower surfaces of the.

. with a'spur gear 4A which which stock wil l be turned to a stick so that the said rollers are oper ated in opposite directions, the said stick will be fed endways.

Corresponding ends of said shafts 36 are provided with coacting spur gears 39.

he outer end of the shaft is provided with a bevel gear 40 designed to be operated through a pinion zontally andlongitudinally arranged shaft 42, said shaft being mounted in suitable bearings 43 from one side of the base '10. The rear end of the shaft 42 is provided is driven through a pinion 45 from the rear end of the tubular shaft 14, thus providing means whereby a stock of material may be continuously fed at anniform speed to the cutting knives,

round handle the cutter blades are rotated, and of a diameter depend r on the'spacing of the cutting edge o't'the knives.

To automatically control said knives, I have provided a yoke 4-6 designed to operate in the groove 19 oi the collar 18, said yoke having outwardly extending pins 47 which are pivotally mounted in the tree endsof a yoke 48, one end of which is pivoted at 4.9 to the base 10. A lever 50 is connected to the yoke 4-8 and extends forwardly and upwardly, the forward end of said. lever being provided with a cam pin 51 designed to run in a cam groove 52 in the cam at 53, said cam gear being mounted on a transversely arranged shaft 54:. The gear 53 is operated from the top one of the gears 39 through the idler gear 55, said idlcrbeing mounted in .1 swinging arm 56, one end of which is pivotally mountedon the shaft 35. This provides means whereby cam gears of various diameters may he applied to the cam shaft 54 for driving the same. Cams of various shapes may also be detachably applied to the shaft 54. U

Thus it will be seen that when the shaft 14 is rotated the cutters 27 will be rotated and also the cam 53 through the gearing mechanism above described. Vhen the said cam 53 is operated, the arm 50. will be rocked, causingthe sleeve 18-to move to- Ward "or fromtlie disk 16, and in turn the cutting edges of the knives 27 may be moved toward or froineach otherl By forming the cam groove 5201? various I i shapes, it will be seen that handles o'fvariou's designs may be formed 'autoniaticallv as the lathe is operated. If iris desireddto produce a longer handle of thesanie design. then the operator removes the'cam gear and placesa larger one in its place,- ori't' it is desired to produce a handle of a different desigmthe operator removes the cam and replaces it with a pattern ofa different design, all ofwhich may be easily and quickly accomplished witlioutmaking any change or adjustments in the lathe itself,

35 and 41 mounted on a hori-' handle Thus it will be seen thatI have provided a lathe of simple, durable and inexpensive construction, which is adapted to automatically feed and turn handles of various shapes and designs on a square stick of material, whiclrniay be easily and quickly placed within the trough provided for that purpose.

It will further be seen that I have pro- Vided an improved knife which will enable the operator to form a complete and finished by one movement of the stock through the trough 32 and the tubular shaft 14. That is,the handle is completed in one operation. a

By providing the stock trough, it will be seen that I have provided means whereby one size stock may be usedto make handles of various sizes. It will also provide means for rigidly snpporting: the stock while it is being turned. Handles of any desired chattering or length may be turned without springing, due to the factth'at the'delivery end ofthe trough is located near the cutting blades.

y providing a series of cutters arranged in a radial manner, I have provided fineans whereby work will. be done very rapidly, due to the fact that a number of cuts take place eachtime the shaft 14 makes a single revolu tion, which greatly increases the speed of the work over the ordinary lathe where a single stationary blade is employed. The cutter blades being arranged in a radial and opposite. manner provides means whereby a uniform lateral cutting pressure is applied to the stock. This also helps to eliminate chattering.

By providing the V-shaped knives having the forward faces extending forwardlyand outwardly, Ihave provided means-whereby the stock will be cut transversely as well as longitudinally, makinga clean out asthey go. This prevents sliveij'ing and splitting. I claim as my invention; Ina device-"of the class described, a tubularj shaft, a cutter device secured to one end ofsaid shaft to rotatein unison therewith, said cutter device comprising a disk having its outer face provided with a seies of radially arranged gnide members, a shank member pivoted to the outer end of-each of said guide members, the inner end ofeach of said shanks j' being provided with a cutter knife, a. sleeve slidably mounted on said shaft, a linkt'orthe inner end of each otsaid shankslf said links extending through said disk and longitudinally of said shaft and having their inner ends connected to said sleevefa lever i'i'iechz'inism forsliding said sleevelongitudinally withsaid shaft and to impartmoyement to the inner ends of said cutterstowardand from said disk and'towardand fromv each other. i
